What Lighting System Does the 1991 Isuzu Amigo Have?
The 1991 Isuzu Amigo features an extensive lighting system with 13 bulb positions. It uses halogen technology with H6054 LED low beams and 74 high beams in a dual-bulb configuration. The Amigo has been available from 1990 to 1994, and the 1991 model falls in the early-generation years.
Can You Put LED Bulbs in a 1991 Isuzu Amigo?
To upgrade the 1991 Isuzu Amigo headlights to LED, you will need a H6054 LED LED kit for the low beams and a 74 LED kit for the high beams. Start with the low beams since they are used most often and have the biggest impact on nighttime visibility. For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 1991 Isuzu Amigo
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Older model years like the 1991 Amigo typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the LED Fog Light fog light socket.

Standard halogen headlights on the 1991 Isuzu Amigo have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 35 years old, the original bulbs on your Amigo are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.
What Bulbs Are Compatible with the 1991 Isuzu Amigo?
The H6054 low beam bulb on the 1991 Isuzu Amigo is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact H6054 size.

It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.
